[0001] This application claims priority to Chinese Patent Application No. 202210227347.4, filed with the China National Intellectual Property Administration on March 8, 2022 and entitled "KNOWLEDGE UPDATE METHOD AND COMMUNICATION APPARATUS", which is incorporated herein by reference in its entirety.
TECHNICAL FIELD
[0002] This application relates to the field of communication technologies, and more specifically, to a knowledge update method and a communication apparatus.
BACKGROUND
[0003] Currently, users can do automation work with a cognitive network management system. The cognitive network management system may include a knowledge provision network element, a knowledge consumption network element, and a network management network element. The network management network element may deliver an intent to the knowledge consumption network element, to meet an expectation for an action system, for example, to make a performance indicator of the action system reach a threshold. The knowledge consumption network element may generate at least one intent operation based on intent knowledge provided by the knowledge provision network element, and deliver the at least one intent operation to at least one network device for execution. In a process in which the network device executes the intent operation, the knowledge consumption network element may obtain a change value of a performance indicator of the network device, so that the knowledge provision network element can update the intent knowledge of the intent operation based on the change value. In this way, in a subsequent intent execution procedure, the system can determine an appropriate intent operation based on updated intent knowledge.
[0004] However, if quality of the intent knowledge updated by the knowledge provision network element is low, the system may execute an inappropriate intent operation based on the low-quality intent knowledge in the subsequent intent execution procedure, and consequently cannot normally execute the intent to meet the expectation for the action system.

[0075] FIG. 1 is a diagram of a structure of a communication system to which an embodiment of this application is applicable. Apparatuses that may be related in the communication system are first described.
- 1. A knowledge provision network element 110 may also be referred to as a knowledge
management (knowledge management, KM) network element, and may be configured to manage
knowledge, for example, provide services such as knowledge storage, knowledge query,
and knowledge update. In this embodiment of this application, the knowledge management
network element may provide a knowledge service for a knowledge consumption network
element 130. In this way, during analysis, the knowledge consumption network element
130 may refer to expertise and knowledge provided by the knowledge provision network
element 110.
It should be understood that in a communication system (for example, a wIDN system or an IDMS system) for intent execution, the knowledge managed by the knowledge provision network element 110 may be intent knowledge. In another communication system, for example, a system in which an artificial intelligence (artificial intelligence, AI) model or a machine learning (machine learning, ML) model runs, the knowledge managed by the knowledge provision network element 110 may alternatively be expertise and knowledge of the model. In the following embodiments, the intent knowledge is used as an example for description. - 2. A network management network element 120 can be responsible for network operations, management, and maintenance. For example, the network management network element 120 may send a request for implementing an intent to the knowledge consumption network element 130, and the network management network element 120 may further deliver initial intent knowledge to the knowledge provision network element 110. In some communication systems, the network management network element 120 may be a network management system (network management system, NMS), a service consumer, or a management service (management service, MnS) network element. In a future communication system or another communication system, the network management network element 120 may have another name, or may have another function. This is not particularly limited in this application.
- 3. A knowledge consumption network element 130 may be used for intent execution. For example, the knowledge consumption network element 130 may receive a request for implementing an intent, query, based on the intent, the knowledge provision network element 110 for related intent knowledge to generate an intent operation, and deliver the intent operation to at least one network device. In some communication systems, the knowledge consumption network element 130 may be an intent driven management function (intent driven management function, IDMF) network element. In a future communication system or another communication system, the knowledge consumption network element 130 may have another name, or may have another function. This is not particularly limited in this application.
[0076] In addition, in some communication systems, the knowledge consumption network element 130 may be deployed on a device management network element, an element management system, or an equipment management system (equipment management system, EMS). The device management network element, the element management system, or the EMS may further include a data collection coordination network element, where the data collection coordination network element may be configured to collect data. For example, the data collection coordination network element may receive a KPI subscription request from the knowledge consumption network element 130, and collect a KPI value of one or more network devices based on the KPI subscription request for KPI reporting. In some communication systems, the data collection coordination network element may be a data collection coordination function (data collection coordination function, DCCF) network element. In a future communication system or another communication system, the data collection coordination network element may have another name, or may have another function. This is not particularly limited in this application.
[0077] It should be noted that the solutions in this application may be applied to another system including a corresponding network element. This is not limited in this application. It may be understood that the foregoing network elements or functions may be network elements in a hardware device, may be software functions running on dedicated hardware, or may be virtualized functions instantiated on a platform (for example, a cloud platform). Optionally, the foregoing network elements or functions may be implemented by one device, may be jointly implemented by a plurality of devices, or may be implemented by one functional module in one device. This is not specifically limited in embodiments of this application.
[0078] When the network device executes an intent operation, the knowledge consumption network element may obtain a change value of a performance indicator of the network device, and generate intent knowledge of the intent operation based on the change value. However, the network device may execute a plurality of intent operations in a same time period, and the change value of the performance indicator may be a result of the plurality of intent operations. The intent knowledge of the intent operation generated by the knowledge consumption network element may be affected by another intent operation. Consequently, an inappropriate intent operation may be generated in a subsequent intent execution procedure of a system, and an expectation for an action system cannot be met. The following first describes a knowledge update method with reference to FIG. 2.
[0080] S201. An NMS network element sends a knowledge repository initialization message to a KM network element.
[0081] The knowledge repository initialization message includes intent knowledge, where the intent knowledge may be impact of each of a plurality of intent operations on a KPI value of a system. The KM network element may initialize a knowledge repository in the KM network element based on the knowledge repository initialization message. For example, the KM network element may store the intent knowledge in the knowledge repository.
[0082] S202. The KM network element sends a knowledge repository initialization acknowledgment message to the NMS network element in response to the knowledge repository initialization message.
[0083] S203. The NMS network element sends an intent creation request message to an IDMF network element.
[0084] The intent creation request message is used to request to create a first intent. For example, the intent creation request message may include an intent expression of the first intent. The IDMF network element may generate at least one intent solution based on the intent expression, where each intent solution includes at least one intent operation.
[0085] S204. The IDMF network element sends an operation solution impact query request message to the KM network element.
[0086] The operation solution impact query request message may be used to query impact of each of the at least one intent solution on the system. For example, the operation solution impact query request message carries identification information of the at least one intent solution.
[0087] S205. The KM network element sends an operation solution impact query feedback message to the IDMF network element in response to the operation solution impact query request message.
[0088] The operation solution impact query feedback message may be used to return the impact of the at least one intent solution on the system. For example, the KM network element may query impact of the intent operation in each intent solution on the system, to generate the operation solution impact query feedback message.
[0089] S206. The IDMF network element determines a target intent solution based on the operation solution impact query feedback message.
[0090] For example, the IDMF network element selects an appropriate intent solution from the at least one intent solution as a target intent solution based on the operation solution impact query feedback message, and executes the target intent solution.
[0092] The IDMF network element delivers a corresponding intent operation to at least one network device based on the target intent solution.
[0093] S208. The IDMF network element sends a solution impact KPI subscription request message to a DCCF network element.
[0094] The solution impact KPI subscription request message is used to obtain KPI information of the at least one network device. For example, the solution impact KPI subscription request message may carry identification information of at least one network device that executes the intent operation and a KPI name.
[0095] S209. The DCCF network element sends a solution impact KPI subscription response message to the IDMF network element in response to the solution impact KPI subscription request message.
[0099] The IDMF network element may process (for example, calculate an average value of) at least one change value of the KPI value of the at least one network device during execution of the intent operation, to generate the impact information of the intent operation.
[0100] S211. The IDMF network element sends an operation impact knowledge update request message to the KM network element.
[0101] The operation impact knowledge update request message is used to request the KM network element to update intent knowledge of the intent operation.
[0102] S212. The KM network element updates the intent knowledge of the intent operation based on the operation impact knowledge update request message.
[0103] For example, the KM network element may store the change value of the KPI value in the knowledge repository.
[0104] It can be learned that, in the procedure in the method 200, the intent knowledge of the intent operation is updated in step S212. When executing a subsequent intent, the system determines the to-be-executed target intent solution based on updated intent knowledge. However, in step S210 (the IDMF network element determines impact information based on the KPI information), the KPI information means change values of KPI values of all network devices executing the intent operation in an entire time period in which the intent operation is executed. In a scenario in which a network device simultaneously executes another intent operation, intent knowledge obtained by the IDMF network element is inaccurate. Consequently, when executing the subsequent intent, the system cannot determine an appropriate intent solution based on the intent knowledge. The following describes the scenario with reference to FIG. 3.
[0105] FIG. 3 is a diagram in which a communication system executes two intent solutions. Refer to FIG. 3. The communication system executes an intent solution A and an intent solution B.
[0106] The intent solution A is used for throughput optimization. The intent solution A includes an intent operation A. The intent operation A is enabling downlink 265QAM. The intent solution A is as follows: A network device 1 to a network device 10 execute the intent operation A in a first time period.
[0107] The intent solution B is used for energy saving. The intent solution B includes an intent operation B. The intent operation B is enabling intelligent carrier shutdown. The intent solution B is as follows: A network device 6 to a network device 15 execute the intent operation B in a second time period.
[0108] The first time period and the second time period have an overlapping time period. For ease of description, in this embodiment of this application, the first time period excluding the overlapping time period is described as a time period #1, the overlapping time period is described as a time period #2, and the second time period excluding the overlapping time period is described as a time period #3. Details are not described below.
[0110] The IDMF network element obtains first KPI information, where an average change value of downlink throughputs of the network devices 1 to 10 in the first time period is increased by 20%.
[0111] The KM network element determines intent knowledge of the intent operation A based on the first KPI information, where executing the intent operation A causes a downlink throughput of the system to be increased by 20%.
[0112] The IDMF network element obtains second KPI information, where an average change value of downlink throughputs of the network devices 6 to 15 in the second time period is decreased by 10%.
[0113] The KM network element determines intent knowledge of the intent operation B based on the second KPI information, where executing the intent operation B causes the downlink throughput of the system to be decreased by 20%.
[0114] However, because the network devices 6 to 10 simultaneously execute the intent operation A and the intent operation B in the time period #2, intent knowledge, of the intent operation A, updated according to the method 200 includes impact information of the intent operation B, and intent knowledge, of the intent operation B, updated according to the method 200 includes impact information of the intent operation A, causing low accuracy of the updated intent knowledge. In view of this, a knowledge update method and a communication apparatus are urgently needed, to improve accuracy of updated knowledge. The following first describes the knowledge update method with reference to FIG. 4.
[0115] FIG. 4 is a schematic flowchart of a knowledge update method 400 according to an embodiment of this application.
[0116] S410. A knowledge provision network element sends knowledge information to a network management network element, and correspondingly, the network management network element receives the knowledge information from the knowledge provision network element.
[0118] The intent knowledge of the first intent operation may be intent knowledge determined by the knowledge provision network element based on a policy in a process of executing the first intent operation. The policy may be a policy sent by the network management network element to the knowledge provision network element during initialization, or a policy sent by the network management network element to the knowledge provision network element before the intent knowledge is determined this time.
[0119] Optionally, the first intent operation is a single intent operation or an intent operation combination including a plurality of intent operations.
[0120] It should be understood that when the first intent operation is the intent operation combination including the plurality of intent operations, the system may manage the intent knowledge at a granularity of the intent operation combination. For example, the first intent operation is an intent combination including an intent operation A and an intent operation B, and the intent knowledge describes impact of simultaneously executing the intent operation A and the intent operation B on the system.
[0121] Optionally, the knowledge information includes at least one of the following information: the intent knowledge, a manner of determining the intent knowledge, time when the intent knowledge is determined, original intent knowledge of the first intent operation before the intent knowledge is determined, and change information of the intent knowledge.
[0122] For example, the network management network element determines the quality of the intent knowledge based on a change value between the intent knowledge and the original intent knowledge. In addition, when the knowledge provision network element determines a plurality of pieces of intent knowledge of the first intent operation for a plurality of times, the original intent knowledge may include a plurality of pieces of historical intent knowledge determined for a plurality of times before intent knowledge determined this time, so that the network management network element may determine the quality of the intent knowledge based on a change variance of the plurality of pieces of intent knowledge. By way of example but not limitation, when the change variance is large, it may be considered that the quality of the intent knowledge is poor.
[0123] Alternatively, in another example, the knowledge provision network element generates a plurality of pieces of intent knowledge for a plurality of times based on a predetermined policy, and determines the change information of the intent knowledge based on the plurality of pieces of intent knowledge generated for the plurality of times, so that the network management network element may determine the quality of the intent knowledge based on the change information.
[0124] Alternatively, optionally, the knowledge information includes a quality value of the intent knowledge. In other words, after determining the quality value of the intent knowledge, the knowledge provision network element sends the quality value to the network management network element.
[0125] It should be understood that the knowledge information may further include another parameter that can reflect the quality of the knowledge. A manner in which the knowledge information indicates the quality is not particularly limited in this application.
[0126] In a possible implementation, the knowledge information may be quality of intent knowledge executed currently or in a specific time period. For example, the knowledge information indicates that the quality of the intent knowledge is lower than a preset value, and the network management network element may learn, according to a preset rule, that quality of intent knowledge of an intent operation that is currently in an execution state is lower than the preset value.
[0127] S420. The network management network element sends policy information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the policy information from the network management network element.
[0129] Optionally, before the network management network element sends the policy information to the knowledge provision network element, the network management network element determines the policy information based on the knowledge information.
[0130] For example, when the knowledge information indicates that the quality of the intent knowledge does not meet expectations, the network management network element may redetermine or adjust a manner of determining the intent knowledge, generate the policy information, and send the policy information to the knowledge provision network element.
[0131] Optionally, the policy information further indicates a manner of determining at least one target network device and a target time period.
[0132] The target network device is one or more of network devices executing the first intent operation, and the target time period is all or some time periods in which the first intent operation is executed. Further, the knowledge provision network element may update the intent knowledge based on a change value of a performance indicator of the target network device in the target time period.
[0133] Optionally, in the target time period, the target network device executes the first intent operation, and does not execute an intent operation other than the first intent operation.
[0134] For example, in the communication system shown in FIG. 3, when the first intent operation is the intent operation A, the network devices 1 to 5 execute only the intent operation A in the time period #1 and the time period #2, and the network devices 6 to 10 execute only the intent operation A in the time period #1; when the first intent operation is the intent operation B, the network devices 6 to 10 execute only the intent operation B in the time period #2, and the network devices 11 to 15 execute only the intent operation B in the time period #2 and the time period #3; or when the first intent operation is an operation combination including the intent operation A and the intent operation B, the network devices 6 to 10 execute the intent operation A and the intent operation B in the time period #2.
[0136] First policy: A longest time period in which only the intent operation in the intent operation combination is executed is the target time period, and a network device that executes only the intent operation in the intent operation combination in the target time period is the target network device.
[0137] For example, in the communication system shown in FIG. 3, the device management network element determines intent knowledge of the intent operation Abased on change values of performance indicators of the network devices 1 to 5 in the time period #1 and the time period #2.
[0138] Second policy: A time period in which there is a maximum quantity of network devices that execute only the intent operation in the intent operation combination is the target time period, and a network device that executes only the intent operation in the intent operation combination in the target time period is the target network device.
[0139] For example, in the communication system shown in FIG. 3, the device management network element determines intent knowledge of the intent operation Abased on change values of performance indicators of the network devices 1 to 10 in the time period #1.
[0140] Third policy: A network device that executes only the intent operation in the intent operation combination in a time period is the target network device, and the target time period corresponding to the target network device is the time period in which only the intent operation in the intent operation combination is executed.
[0141] For example, in the communication system shown in FIG. 3, the device management network element determines intent knowledge of the intent operation Abased on change values of performance indicators of the network devices 1 to 5 in the time period #1 and the time period #2 and change values of performance indicators of the network devices 6 to 10 in the time period #1.
[0142] It should be understood that the first policy may be a policy on a time range priority, the second policy may be a policy on a space range priority, and the third policy may be a policy on a collection point quantity priority. The foregoing policies are merely an example for description. Embodiments of this application may further include another policy for selecting the target network device and the target time period.
[0143] Therefore, the device management network element receives the policy information, and may select an appropriate policy based on the policy information to obtain the change value of the performance indicator of the target network device in the target time period, to determine intent knowledge of a corresponding intent operation.
[0145] For example, when the policy information includes a plurality of policies, the policy information may further indicate a priority order of the plurality of policies.
[0146] Optionally, the policy information further includes at least one of the following constraint conditions: a quantity of target network devices is greater than or equal to a first threshold, and a length of the target time period is greater than or equal to a second threshold.
[0147] For example, in the communication system shown in FIG. 3, in a process in which the device management network element determines the intent knowledge of the intent operation A, if the policy information indicates that a quantity of target network devices is greater than or equal to 6, the device management network element needs to select at least six network devices from the network devices 1 to 10 as target network devices. For example, the device management network element may determine the intent knowledge of the intent operation A by using the second policy or the third policy.
[0148] Alternatively, in another example, in the communication system shown in FIG. 3, the first information includes the three policies, and priorities of the three policies are as follows: A priority of the first policy is higher than a priority of the second policy, and the priority of the second policy is higher than a priority of the third policy. In a process in which the device management network element determines the intent knowledge of the intent operation A, if the first information indicates that a quantity of target access networks is greater than or equal to 6, the device management network element cannot meet a constraint condition by using the first policy, and the device management network element needs to use the second policy to determine the intent knowledge of the intent operation A.
[0149] Optionally, the policy information further indicates to determine the first intent operation.
[0150] For example, the policy information includes a maximum quantity of overlapping operations, and the knowledge provision network element updates the intent knowledge of the first intent operation whose overlapping operation quantity is less than or equal to the maximum quantity of overlapping operations. By way of example but not limitation, in the communication system shown in FIG. 3, if the maximum quantity of overlapping operations is 1, the knowledge provision network element updates the intent knowledge of the intent operation A and intent knowledge of the intent operation B; or if the maximum quantity of overlapping operations is 2, the knowledge provision network element updates the intent knowledge of the intent operation A, intent knowledge of the intent operation B, and intent knowledge of the operation combination of the intent operation A and the intent operation B.
[0151] Optionally, the policy information corresponds to identification information of the first intent operation.
[0152] The identification information of the first intent operation may be an identifier of the first intent operation, an identifier of a first intent solution to which the first intent operation belongs, or an identifier of an intent to which the first intent operation belongs.
[0153] For example, the policy information includes general policy information and special policy information. The general policy information and the special policy information may include different policies, constraint conditions, and the like. The knowledge provision network element may determine, based on the identification information of the first intent operation, whether to use the general policy information or the special policy information.
[0154] Optionally, in S430, the knowledge provision network element obtains performance evaluation information.
[0155] The performance evaluation information further indicates a change value of a performance indicator of the at least one target network device in the target time period.
[0156] There may be two manners in which the knowledge provision network element obtains the performance evaluation information. The following describes the two manners with reference to FIG. 5.
Manner a:
[0157] S431a. The knowledge provision network element sends the policy information to a knowledge consumption network element, and correspondingly, the knowledge consumption network element receives the policy information from the knowledge provision network element.
[0158] S432a. The knowledge consumption network element sends a KPI subscription request message to a DCCF network element, and correspondingly, the DCCF network element receives the KPI subscription request message from the knowledge consumption network element.
[0159] The KPI subscription request message is used to request a KPI value of at least one network device. For example, the KPI subscription request message may include a KPI name and identification information of the at least one network device. The at least one network device may be a network device managed by the knowledge consumption network element. Alternatively, the knowledge consumption network element may determine the target network device and the target time period based on the policy information, and request a KPI value of the target network device in the target time period.
[0160] S433a. The DCCF network element sends KPI information to the knowledge consumption network element, and correspondingly, the knowledge consumption network element receives the KPI information from the DCCF network element.
[0161] For example, the DCCF network element may return the requested KPI value of the network device to the knowledge consumption network element in response to the KPI subscription request message. The KPI information may include a reported KPI name, a collection object (namely, a requested network device), and a KPI value.
[0162] The DCCF network element may periodically return collected KPI values to the knowledge consumption network element for a plurality of times. Alternatively, after collecting KPI values for a plurality of times, the DCCF network element may return the KPI values collected for the plurality of times to the knowledge consumption network element at a time. This is not particularly limited in this application.
[0163] S434a. The knowledge consumption network element determines the performance evaluation information based on the KPI information.
[0164] For example, if the KPI information includes a KPI value of the at least one network device managed by the knowledge consumption network element, the knowledge consumption network element may determine a KPI value of the target network device based on the policy information.
[0165] S435a. The knowledge consumption network element sends the performance evaluation information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the performance evaluation information from the knowledge consumption network element.
[0166] Further, the knowledge provision network element obtains the performance evaluation information from the knowledge consumption network element.
[0167] Therefore, in Manner a, the knowledge provision network element may send the policy information to the knowledge consumption network element, and the knowledge consumption network element determines the performance evaluation information based on the policy information, and sends the performance evaluation information to the knowledge provision network element.
Manner b:
[0168] Optionally, in S431b, a knowledge consumption network element sends operation execution information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the operation execution information from the knowledge consumption network element.
[0169] The operation execution information indicates a network device executing the first intent operation and a time period for executing the first intent operation, or the operation execution information indicates an intent operation currently being executed in a system, and a network device executing the intent operation and a time period for executing the intent operation, or the operation execution information indicates an intent solution currently being executed in a system. For example, the operation execution information includes at least one of the following information: identification information of an intent solution (or an intent operation), time information of executing the intent solution (or the intent operation), and a network device executing the intent solution (or the intent operation).
[0170] S432b. The knowledge provision network element determines the at least one target network device and the target time period based on the policy information.
[0171] For example, the knowledge provision network element may determine the target network device and the target time period based on a policy and a constraint condition that are included in the policy information. When the knowledge consumption network element further sends the operation execution information to the knowledge provision network element, the knowledge provision network element may determine the target network device and the target time period based on the operation execution information and the policy information.
[0172] S433b. The knowledge provision network element sends a KPI query request message to a DCCF network element, and correspondingly, the DCCF network element receives the KPI query request message from the knowledge provision network element.
[0173] The KPI query request message may be used to request a KPI value of the target network device in the target time period. For example, the KPI query request message may include a KPI name, identification information of the target network device, and the target time period.
[0174] S434b. The DCCF network element sends KPI information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the KPI information from the DCCF network element.
[0175] The KPI information may indicate KPI values of the target network device at a plurality of collection time points in the target time period. For example, the KPI information may include the KPI name, the identification information of the target network device, the plurality of collection time points, and the corresponding KPI values.
[0176] S435b. The knowledge provision network element determines the performance evaluation information based on the KPI information.
[0177] For example, the knowledge provision network element may determine change values of the KPI values of the target network device in the target time period based on the KPI values of the target network device at the plurality of time points.
[0178] Therefore, in Manner b, the knowledge provision network element may request the DCCF network element to query KPI value of the target network device in the target time period, to determine the performance evaluation information based on the KPI value.
[0180] The confidence information indicates a trustworthiness level of the performance evaluation information.
[0181] The trustworthiness level may indicate accuracy of determining the intent knowledge by the device management network element by selecting the target network device and the target time period. For example, the trustworthiness level may be related to a quantity of selected target network devices, quality of the target network device, a length of the target time period, quality of the target time period, or the performance indicator. For example, when a quantity of sampling points is larger (that is, the quantity of target network devices is larger and/or the target time period is longer), the trustworthiness level is higher.
[0182] Optionally, before the knowledge provision network element obtains the confidence information, the network management network element sends first information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the first information from the network management network element.
[0183] The first information indicates a manner of determining the confidence information. The knowledge provision network element may obtain the confidence information based on the first information.
[0184] There may be three manners in which the knowledge provision network element obtains the confidence information. The following describes the three manners with reference to FIG. 6.
Manner a:
[0185] S441a. The knowledge provision network element sends the first information to the knowledge consumption network element, and correspondingly, the knowledge consumption network element receives the first information from the knowledge provision network element.
[0187] S442a. The knowledge consumption network element determines the confidence information based on the first information.
[0188] For example, the knowledge consumption network element may determine a confidence level in the manner that is of determining the confidence information and that is indicated by the first information based on the quantity of target network devices, the length of the target time period, the change variance of the KPI values, or the like.
[0189] S443a. The knowledge consumption network element sends the confidence information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the confidence information from the knowledge consumption network element.
[0190] Optionally, when the trustworthiness level is greater than or equal to a third threshold, the knowledge consumption network element sends the performance evaluation information to the knowledge provision network element; or when the trustworthiness level is less than a third threshold, the knowledge consumption network element may send, to the knowledge provision network element, information indicating that the trustworthiness level of the performance evaluation information is not high, so that the knowledge provision network element or the network management network element may adjust the manner of determining the confidence information. Optionally, the first information further indicates the third threshold.
[0191] Therefore, the knowledge provision network element may send the manner of determining the confidence information to the knowledge consumption network element, and the knowledge consumption network element determines the confidence information and sends the confidence information to the knowledge provision network element.
Manner b:
[0192] Optionally, in S441b, the knowledge provision network element sends confidence factor calculation information to the knowledge consumption network element based on the first information, and correspondingly, the knowledge consumption network element receives the confidence factor calculation information from the knowledge provision network element.
[0193] The confidence factor calculation information indicates a manner of determining a confidence factor. Alternatively, the confidence factor indicates a form of the confidence factor (for example, a form such as time, a quantity of network devices, or a quantity of sampling points). Alternatively, the confidence factor calculation information indicates the knowledge consumption network element to feed back a value of a confidence factor based on the performance evaluation information, where the confidence factor is a factor required for calculating a confidence level. For example, the confidence factor may include the length of the target time period, the quantity of target network devices, the quantity of sampling points, and the like.
[0194] The knowledge provision network element may parse the first information to obtain the confidence factor calculation information. For example, if the first information indicates that a confidence level calculation manner is as follows: Confidence level = max(1, time range/24 hours), the knowledge provision network element may determine that the confidence factor calculation information includes time information.
[0196] The knowledge consumption network element may determine the value of the confidence factor by obtaining a network sampling point corresponding to the performance evaluation information. For example, when the knowledge provision network element sends the confidence factor calculation information to the knowledge consumption network element, and the confidence factor calculation information indicates that the confidence factor is the time information, the knowledge consumption network element may use a time interval (for example, a time interval between sampling start time and sampling end time) of the network sampling point corresponding to the performance evaluation information as the value of the confidence factor.
[0197] S443b. The knowledge consumption network element sends the confidence factor to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the confidence factor from the knowledge consumption network element.
[0198] For example, the knowledge consumption network element sends the value of the confidence factor to the knowledge provision network element.
[0199] S444b. The knowledge provision network element determines the confidence information based on the first information and the confidence factor.
[0200] Therefore, in Manner b, the knowledge provision network element may obtain, based on the first information, the confidence factor required for determining the confidence level, and send the manner of determining the confidence factor to the knowledge consumption network element. Further, after receiving the confidence factor from the knowledge consumption network element, the knowledge provision network element may determine the confidence information based on the confidence factor.
Manner c:
[0201] Optionally, in S441c, the knowledge consumption network element sends operation execution information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the operation execution information from the knowledge consumption network element.
[0202] The operation execution information indicates a network device executing the first intent operation and a time period for executing the first intent operation, or the operation execution information indicates an intent operation currently being executed in a system, and a network device executing the intent operation and a time period for executing the intent operation, or the operation execution information indicates an intent solution currently being executed in a system. For example, the operation execution information includes at least one of the following information: identification information of an intent solution (or an intent operation), time information of executing the intent solution (or the intent operation), and a network device executing the intent solution (or the intent operation).
[0203] S442c. The knowledge provision network element determines the at least one target network device and the target time period based on the policy information.
[0204] For example, the knowledge provision network element may determine the target network device and the target time period based on a policy and a constraint condition that are included in the policy information. When the knowledge consumption network element further sends the operation execution information to the knowledge provision network element, the knowledge provision network element may determine the target network device and the target time period based on the operation execution information and the policy information.
[0205] S443c. The knowledge provision network element sends a KPI query request message to a DCCF network element, and correspondingly, the DCCF network element receives the KPI query request message from the knowledge provision network element.
[0206] The KPI query request message may be used to request a KPI value of the target network device in the target time period. This step may be similar to step S432b, and details are not described herein again.
[0207] S444c. The DCCF network element sends KPI information to the knowledge provision network element, and correspondingly, the knowledge provision network element receives the KPI information from the DCCF network element.
[0208] The KPI information may indicate KPI values of the target network device at a plurality of collection time points in the target time period. This step may be similar to step S433b, and details are not described herein again.
[0209] S445c. The knowledge provision network element determines the confidence information based on the first information and the KPI information.
[0210] Therefore, in Manner c, the knowledge provision network element may request the DCCF network element to query KPI value of the target network device in the target time period, and determine the confidence information based on the KPI information and the first information.
[0212] For example, the knowledge provision network element may obtain historical intent knowledge of the first intent operation in a knowledge repository based on the performance evaluation information, and then process the performance evaluation information based on a knowledge update algorithm, to determine new intent knowledge and update the knowledge in the knowledge repository.
[0213] The knowledge provision network element may preset the knowledge update algorithm, or the network management network element may send, to the knowledge provision network element, information indicating the knowledge update algorithm.
[0214] Optionally, the knowledge provision network element determines, based on the confidence information, whether to update the intent knowledge. When a trustworthiness level indicated by the confidence information is greater than or equal to a predetermined threshold, the knowledge provision network element updates the intent knowledge based on the performance evaluation information. Alternatively, when a trustworthiness level indicated by the confidence information is less than a predetermined threshold, the knowledge provision network element does not update the intent knowledge.
[0215] Alternatively, optionally, the knowledge provision network element determines updated intent knowledge based on the confidence information and the performance evaluation information. For example, the knowledge provision network element determines a weighting coefficient of the historical intent knowledge and current performance evaluation information based on the trustworthiness level indicated by the confidence information, and updates the intent knowledge based on the weighting coefficient.
[0216] In this way, in this application, the knowledge provision network element may feed back the quality of the intent knowledge to the network management network element, the network management network element may deliver, to the knowledge provision network element based on the quality, the manner of updating the intent knowledge, and the knowledge provision network element may perform updating based on the policy information in a subsequent intent knowledge update procedure, to improve quality of the updated knowledge.
[0217] FIG. 7 is a schematic flowchart of a knowledge update method 700 according to an embodiment of this application.
[0218] S701. A knowledge provision network element sends knowledge information to a network management network element, and correspondingly, the network management network element receives the knowledge information from the knowledge provision network element.
[0219] The knowledge information indicates quality of intent knowledge of a first intent operation. For descriptions of this step, refer to the descriptions of step S410 in the method 400. For brevity, details are not described herein again.
